Recommended actionError condition
Verify the following:The logical devices are not
recognized by the host.
• The READY indicator lights on the disk array are ON.
• Fiber cables are correctly installed and firmly connected.
• The target IDs are properly configured. The LUNs for each TID must
start at 0 and continue sequentially without skipping any numbers.
• The TIDs/WWNs on each bus are unique. Do not install two
devices with the same ID on the same bus. Recheck the buses for
new devices.
• LUSE devices are not intermixed with normal LUNs on the same
port.
• The maximum number of LUSE devices per port has not been
exceeded.
• The disk array host mode is set correctly.
If you power off the host without executing the shutdown process, wait
three minutes to allow the disk array's internal timeout process to purge
queued commands. If the host restarts while the disk array is processing
queued commands, the host may not reboot successfully.
The host does not reboot properly
after hard shutdown.
Verify that the disk array logical devices are correctly formatted.Physical volumes cannot be created.
Verify that the volume capacity for OPEN-x volumes is not greater than
the maximum capacity allowed. See “Disk array supported
emulations” on page 29.
Logical volumes cannot be created.
Verify that the capacity of the volume group is not less than the total
capacity of the partitioned logical volume.
Verify that the host was restarted correctly.A file system is not mounted after
rebooting.
Verify that the file system attributes are correct.
